MOLDERS DRAW=|RON.

SPECIFICATION forming part of Letters Patent No. 383,203,. dated May 22,1888.

Application filed April 4, 1887. Serial No. 233,592.

To all whom it may concern.-

Be it known that I, GEORGE ALDEN WHITE, of Sharon, in the county ofNorfolk and State of Massachusetts, have invented new and ImprovedMolders Draw-Irons, of which the following is a full, clear, and exactdescription.

My invention relates to a draw iron for niolders use; and the object ofthe invention I0 is to provide a device for the ready and accuratewithdrawal of a pattern from the mold, and wherein the screw may bereplaced when worn in a short time and at little cost.

The invent-ion consists in the construction and combination of theseveral parts of the iron, as will be hereinafter fully set forth, andpointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar letters of reference indicate corresponding parts inall the figures.

Figure l is a side elevation,partlyin section, of the draw-iron; andFig. 2, a horizontal section on line a: 00 of Fig. 1, looking down. Fig.

3 is a horizontal section, upon line :0 x of Fig.

1, through the driver, looking up.

In carrying out the object of the invention, a thimble, A, isconstructed, preferably eir eular in form, having below the center ahexagoual head, a, whereby a wrench or key may be used, and a reducedlower end below said head.

From a point corresponding with the upper surface of the head a upwardthe thimble A is 5 tubular, the upper portion, B, being threaded and thelower portion formed in a chamber,O. From the chamber 0, leadingcentrally downward through the lower end of the thimble,an aperture, d,is provided about the diameter of an ordinary wood-screw, and thatportion of No model.)

the said aperture (2 leading in the chamber O .is inclined upward andoutward to form a countersink, d, for the head of the woodscrew D,adapted to enter the aperture (2, as illustrated.

A circular handle, E, is formed with a threaded shank, E, having acentral vertical angularsocket, into which fits the stem of thedetachable screw-driver E". If the screwdriver should get broken orrequire sharpening, it may be readily removed. The lower end of shank Eis entered into the thimble A and screwed to its threaded portion, thescrew driver engaging the slot in the screw D, as shown in Fig. l.

In operation the wood screw is made to enter the pattern, and by meansof the attachment of the handle with the screw the said screw may be socontrolled in entering thepat tern as not to depress or jar the same andthereby trouble the sand.

One great advantage of my drawiron con sists in the fact that ordinarywoodscrews are employed, and therefore as one screw wears out it may bequickly replaced at a minimum 65 cost.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a molders draw-iron, the combination, with the internallyt-hreadedthi-mble having a removable wood-screw projecting there. through, of thehandle having a threaded shank provided with a socket, and a detachablescrew-driver fitting in said socket and en- 7 gaging the screw,substantially as set forth. GEORGE ALDEN WHITE.
